Cost Reaches $1.5 Trillion, Double the Amount Approved
The US wars in Iraq and Afghanistan are costing nearly double the amount previously thought, according to a report by Democrats in the US Congress.
They say â€œhidden costsâ€ have pushed the total to about $1.5 trillion – nearly twice the requested $804bn (Â£402bn).
Higher oil prices, treating wounded veterans, and the cost to the economy of pulling reservists away from their jobs have been taken into account.
Republicans have not yet commented officially on the report.
And some of the figures it contains were labelled speculative by funding experts, the Washington Post newspaper reported.
The report was written by Democratic members of Congressâ€™s Joint Economic Committee (JEC).
The BBCâ€™s Justin Webb in Washington says the report was designed to shock Americans into stronger opposition to the war in Iraq.
The Democrats calculate that between 2002 and 2008 the campaigns in Iraq and Afghanistan will have cost the average US family of four about $20,900.
The report adds that the amount could rise to $46,400 over the next decade.
It cites costs such as interest payments on money borrowed from abroad to pay for the wars, lost investment in US businesses, and the cost of oil market disruptions.
Oil prices have surged since the start of the war in Iraq, from about $37 a barrel to more than $90 a barrel in recent weeks. The report says the rise has hit US consumers.
The chairman of the JEC, Democratic Senator Chuck Schumer, said the â€œbackbreaking costâ€ of the war was becoming an unbearable burden for American families.
â€œWhat this report makes crystal clear is that the cost to our country in lives lost and dollars spent is tragically unacceptable.â€
He said: â€œThe cost of the war… is becoming the first thing the people mention after the loss of life when they are opposed to this war and the people who mention it, many of them are not people who were against the war in the past.â€
The report estimates that both wars could cost a total of $3.5 trillion over the next decade.
The Democratic authors estimated that treating veterans could add more than $30bn to costs, including disability payments and lost earnings for veterans affected by post-traumatic stress disorder.
